我使用 Angular 2 进行路由，使用节点进行本地托管。
当我为我的路线使用“useAsDefault:true”时，导航栏链接不再有效并且 URL 转到 http://localhost/ (空白页)当我希望它转到 http://localhost/home 时
一个是我删除了导航栏正常工作的标志，我可以转到/home 路线，但我转到了空白页面
谁能解释为什么默认标志无法正常工作？
App.Component.ts
@RouteConfig([
{ path: '/home', name: 'Home', component: HomeComponent /*, useAsDefault : true */},
{ path: '/articles', name: 'Posts', component: PostsComponent },
{ path: '/detail/:id', name: 'PostDetail', component: PostDetailComponent },
{ path: '/login', name: 'Login', component: LoginComponent },
])
App.Component.html
<ul class="topnav">
<li><a [routerLink]="['Home']">Home</a></li>
<li><a [routerLink]="['Posts']">Articles</a></li>
<li><a href="#p">Publisher</a></li>
<li><a [routerLink]="['Login']">Login</a></li>
</ul>
<router-outlet></router-outlet>
Main.ts
import { bootstrap } from '@angular/platform-browser-dynamic';
import { AppComponent } from './app.component';
import { HTTP_PROVIDERS } from '@angular/http';
import { ROUTER_PROVIDERS } from '@angular/router-deprecated';
bootstrap(AppComponent, [ROUTER_PROVIDERS, HTTP_PROVIDERS]);

最佳答案
只需为每个尝试访问的未定义的路由添加一条路由，并将其重定向到您的主路由:
@RouteConfig([
{ path: '/home', name: 'Home', component: HomeComponent },
{ path: '/articles', name: 'Posts', component: PostsComponent },
{ path: '/detail/:id', name: 'PostDetail', component: PostDetailComponent },
{ path: '/login', name: 'Login', component: LoginComponent },
{ path: '/**', redirectTo: ['Home'] }
])
关于javascript - Angular 2 - 路由 useAsDefault 不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37388659/
